The incidence and mortality of the hypopharyngeal cancer in Japan were studied based on "Cancer mortality statistics in Japan between 1973 and 1978" and "Population-based cancer registry between 1967 and 1976" The nation wide survey on the hypopharyngeal cancer was performed between 1978 and 1979, and the data from Department of Otorhinolaryngology of 131 Hospitals were also analyzed.The results were as follows:1) The age adjusted mortality rate per 100, 000 population in the period from 1973 to 1977 was 0.19 for male and 0.07 for female for the hypopharyngeal cancer.2) Between 1978 and 1979, 632 new patients (444 males, 188 females) were reported throughout Japan. The adjusted incidence rate was 0.37 for male and 0.13 for female. The highest incidence was observed at the age range of 65 to 69 years.3) The standardized morbidity rate in the period from 1978 and 1979 demonstrated that the morbidity rate of male showed remarkable difference from that of female in some pre-fectures.
